In 2016, can $1000.00 buy enough operations per second to be approximately equal to the computational power of a human brain?
The development of CPUs didn't quite keep up with Kurzweil's predictions. But if you also allow for GPUs, his prediction for 2009 is pretty accurate.
I think Moore's law slowed down recently and has now been pretty much abandoned by the industry. How much that will affect the 2019 prediction remains to be seen. Maybe the industry will hit its stride again with non-silicon based chips, maybe not.
And, of course, whether hitting Kurzweil's estimate of the computing power of the human brain will make an appreciable difference for the development of Artificial General Intelligence (AGI) is another question altogether.
